Abstract
A sucker attachment device includes a support base, a pivot seat pivotally mounted on the support base, a sucker mounted on the pivot seat, a rotation disk swivelably mounted on the support base, and a receptacle assembly mounted on the rotation disk. The pivot seat has a spherical universal connector pivotally mounted on the support base. The support base has an end portion formed with a spherical pivot recess, and the universal connector is rotatably mounted in the pivot recess of the support base. Thus, when the support base is pivoted relative to the universal connector, the universal connector is rotated in the pivot recess through 360° so that the support base is pivoted relative to the pivot seat to change the angle and direction between the sucker and the receptacle assembly freely.
Claims19
A sucker attachment device comprising:
- a support base, wherein the support base has an inner portion formed with a mounting chamber, wherein the support base has a face provided with two radially opposite sockets each extended into the mounting chamber of the support base;
- a pivot seat pivotally mounted on the support base;
- a sucker mounted on the pivot seat to move in concert with the pivot seat;
- a rotation disk swivelably mounted on the support base, wherein the rotation disk is swivelably mounted in the mounting chamber of the support base, wherein the rotation disk has a first face formed with a plurality of positioning grooves which are arranged in an annular shape;
- a receptacle assembly mounted on the rotation disk;
- two positioning balls each movably mounted in a respective one of the two sockets of the support base and each detachably positioned in a respective one of the positioning grooves of the rotation disk to position the rotation disk on the support base temporarily;
- and
- two elastic members each mounted in a respective one of the two sockets of the support base and each biased between the support base and a respective one of the two positioning balls to push each of the two positioning balls toward the positioning grooves of the rotation disk.
A sucker attachment device comprising:
- a support base;
- a pivot seat pivotally mounted on the support base, wherein the pivot seat has an inner wall formed with an axial hole, wherein the axial hole of the pivot seat has a peripheral wall formed with two radially opposite retaining grooves;
- a sucker mounted on the pivot seat to move in concert with the pivot seat, wherein the sucker has a face provided with a mounting block which is extended through the axial hole of the pivot seat, wherein the mounting block has an inner wall formed with an inner threaded portion, wherein the mounting block has an outer wall formed with two radially opposite retaining lugs secured in the two retaining grooves of the pivot seat respectively, wherein the mounting block is limited in the axial hole of the pivot seat and is non-rotatable relative to the pivot seat, wherein the sucker is mounted on a first face of the pivot seat;
- a rotation disk swivelably mounted on the support base;
- and
- a pressing cap rotatably mounted on the pivot seat and connected with the sucker to press the sucker, wherein the pressing cap is rotatably mounted on a second face of the pivot seat, wherein the pivot seat is sandwiched between the sucker and the pressing cap, wherein the pressing cap has a central portion provided with a threaded tube which is screwed into the inner threaded portion of the mounting block.
